We’re looking for an iOS Engineer to join our global Tech team and help shape the future of our mobile app.

Note: This role is on-site. You’ll be based at our Stockholm headquarters at Repslagargatan 17, Södermalm, working in a hybrid setup.

What you'll do

• Help create a cutting-edge, hyper-personalised health experience by leveraging our extensive food database and rich user insights to deliver the right recommendations at the right time.

• Collaborate side-by-side with world-class designers to build beautifully crafted experiences users genuinely love.

• Build, scale, and continuously elevate Lifesum’s iOS app with an uncompromising focus on quality, performance, and craft.

• Own complex features end-to-end — from idea and architecture to production, optimisation, and iteration.

• Act as a technical force multiplier — championing iOS best practices, reducing tech debt, and raising the engineering bar.

• Proactively drive structural and architectural improvements to ensure scalability and long-term maintainability.

• Mentor others and communicate technical concepts clearly — combining deep engineering excellence with strong product intuition.
  
  

Who you are

You're an iOS engineer who combines technical excellence with strong collaboration and communication skills. You're comfortable navigating change, solving complex problems, and keeping a clear eye on the details without losing sight of the bigger picture

• Expert-level experience building iOS applications with Swift and UIKit

• Solid knowledge of modern iOS patterns and libraries such as Combine, URLSession, Core Data, MVVM, and the Repository pattern. Experience with Swift Concurrency and SwiftUI

• Strong ability to self-organise and manage your workload in line with the needs of a growing startup

• A pragmatic approach: you sweat the details, but know when to balance perfection with progress

• Excellent communication skills: collaborating with developers, product managers, and stakeholders is a core part of the role

• Want your work to have real impact on people's lives, not just ship features
  

Nice to have

• Experience containers and orchestration (we use Kubernetes)

• Experience with CI tooling (we use GitHub Actions)

• Experience from startups or scale-ups (a strong plus)
